Chapter on Rulings on Forgetfulness (Sahw) in Prayer and What Requires Repeating of Prayer

Muhammad bin Ya‘qub, from Ali bin Ibrahim, from his father, from Hammad, from Hariz, from Zurarah: Abu Ja‘far عليه السلام, peace be upon him, said: “When you face the qiblah with your face, do not turn your face away from the qiblah, lest your prayer become invalid. For indeed, Allah سبحانه وتعالى the Exalted said to His Prophet صلى الله عليه وعلى آله وسلم, peace be upon him, regarding the obligatory prayer: ‘So turn your face toward the Sacred Mosque, and wherever you are, turn your faces toward it’ (Surah Baqarah 2:144 & 2:150). And lower your gaze, and do not raise it to the sky, but rather let it be aligned with your face at the place of your prostration."
